Cornering (v): The act of lying down and wrapping one's body around a right angle. The person should fully extend their legs and arms in attempt to be "one" with the angle itself. Right angles can include but not limited to: walls, statues, buildings, furniture, curbs, or anything that could potentially be swaddled.

Term used to describe the act of riding a high performance motorcycle through a corner (or curve) of a closed race track or road course. An expert rider is able to corner his machine at high velocity by increasing the lean angle of the motorcycle while at the same time hanging off of the machine, a technique that is often accompanied by knee dragging.

Cornering is the most difficult skill to master in the sport of motorcycle roadracing.
